    What the sheet says: A manual gearbox (PK5/PK6) whose bearings fail, sometimes from 20,000 km; worn bushes and track-rod ends; brake discs that wear early; broken springs; turbo damage on diesels (more on the 1.5 dCi); high oil consumption on the 2.0 16V (M4R); poor fit of doors, bonnet and trim. The 3.0 dCi V6 is the most fragile engine and the V6s are expensive to repair.

Official recalls: ask before you pay

A recall existing does not mean this car is affected or that it is still outstanding: it depends on the chassis number, the market and the production date.

  1. Ask the seller for the chassis number (VIN): it has 17 characters, appears in the car's documents and can usually also be seen at the base of the windscreen.
  2. Ask an official Renault dealer, or the brand's official website if it lets you check by chassis number, whether each recall has been done or is still outstanding for that VIN.
  3. Manufacturer recalls are normally carried out free of charge by the official service network. If one is outstanding, ask for it to be done before you close the sale.

How to check it: Check the recall by VIN; inspect and replace, reprogram or correct the part named in the recall.

On the test drive: what to look and listen for

0 of 3 checked

Timing system

  • Look out for: Noise or squeal around the belts; if the timing belt breaks, the engine stops suddenly and can be badly damaged.

    Ask them to check: Keep to the timing-belt interval and always replace the full kit (belt, rollers and pulleys); check the auxiliary belt and its pulley.

Timing / injection

  • Look out for: Chain noise at high mileage; loss of power and emissions warnings in town use; injectors that will not come out when removed.

    Ask them to check: Listen to the chain from cold, check injection and emissions codes, and before removing injectors have extraction tools ready. Keep oil changes up to date.

Known weak points

  • Look out for: A manual gearbox (PK5/PK6) whose bearings fail, sometimes from 20,000 km; worn bushes and track-rod ends; brake discs that wear early; broken springs; turbo damage on diesels (more on the 1.5 dCi); high oil consumption on the 2.0 16V (M4R); poor fit of doors, bonnet and trim. The 3.0 dCi V6 is the most fragile engine and the V6s are expensive to repair.

    Ask them to check: Listen for gearbox whine in every gear; check suspension and brakes; measure oil consumption; check the campaign by VIN.
